The Martian moons Deimos (small) and Phobos (large), photographed by Mars Express, 5 November 2009.
An anonymous reader asked me yesterday if I had any Deimos gifs.  Well I didn’t, mostly because I didn’t find any decent Deimos sequences in the Viking archives, but the question reminded me that I hadn’t looked at the proper Mars Express archives (as opposed to its webcam Flickr).  A quick Google turned up an old post on Emily Lakdawalla’s blog, containing a larger version of today’s gif released by the ESA – the raw photos are about 1000 pixels wide.  Both that version and mine have undergone some processing (the ESA’s is better…) to reduce some blur.  In my case I just dimmed any pixel at 0.4 on a 0-1 scale to 0.1.
More Deimos tomorrow!
